Articulation and movement of joints and bones
| Question | Answer |
|---|---|
| Junction between 2 bones | articulation |
| Joint between bones that do not move | synarthroses |
| Skull bones join at these | sutures |
| Type of synarthroses | syndesmosis |
| Joints of bones connected by ligaments | syndesmosis |
| Type of synarthroses | gomphosis |
| Joint in which a process fits into a socket | gomphoses |
| Teeth are held in place by this | Periodontal ligament |
| Joints that allow slight movement | amphiarthroses |
| Pubic symphysis is an example of this joint | amphiarthroses |
| Type of amphiarthroses | symphysis |
| Type of freely moving jonts | diarthroses |
| Found between joints | synovial fluid |
| Largest range of motion | multiaxial |
| Function of synovial joints | weight-bearing |
| Function of synovial joints | movement |
| Decreasing angle between bones | flexion |
| Increasing angle between bones | extension |
| Increasing angle beyond anatomic position | hyperextension |
| Movement away from midline of body | abduction |
| Movement towards midline of body | adduction |
| Movement around a central axis | rotation |
| End of bones moves such to make circle in the air | circumduction |
| Movement so that radius and ulna are parallel | supination |
| Lowering a part of the body | depression |
| Movement involving only the thumb | opposition |
| Digits return to normal position | reposition |
| Raising foot upward at ankle | dorsiflexion |
| Pushing foot downward at ankle | plantar flexion |
| Hip joint | ball and socket |
| Shoulder joint | ball and socket |
| Elbow and knee | hinge joint |
| Middle and distal phalanges | uniaxial joint |
| Pivot joints | uniaxial |
| Example of pivot joint | vertebrae |
| Condyloid joint | ellipsodial joint |
| Condyloid joint | biaxial joint |
| Example of condyloid joint | wrist |
| Type of biaxial joint | saddle joint |
| Multiaxial joint | gliding joint |
| Closed sac with synovial fluid | bursae |
| Bursae found under skin | subcutaneous |
| Bursae between muscles | subfascial |
| Bursae found over a tendon or bony projection | subtendinous |
| Inflammed bursae | bursitis |
| Tennis elbow | bursitis |
| Infammation of a joint | arthritis |
| Mild bacterial infection in joints | rheumatic fever |
| Connective tissue disorder | rheumatoid arthritis |
| Debilitating form of arthritis | rheumatoid |
| Arthritis which fuses bones at the jonts | rheumatoid |
| Inflammation of fibrous connective tissue in a joint | primary fibrositis |
| Primary fibrositis is also called | rheumatism |
| Rheumatism of the lower back | lumbago |
| Degenerative joint disease | osteoarthritis |
| Joint disorder common in overweight people | osteoarthritis |
| Accumulation of uric acid | gout |
| Gout appears commonly in this joint | large toe |
| Joint disorder that can cause kidney damage | gout |
